Integrated Fuel Pump Carb Rebuild Mercury Outboards

[@45-70SBL]

Looking forward on the progress of this project. Good stuff.

[@bobabouuy1505]

Great videos. Im working on my 76 mercury 850 and these are the best videos I've seen.

[@MerCSonL6]

Thank you. Son

[@kelton5020]

Nice video.....I have the exact same dual carb setup on my 83 mercury 50hp.....

[@dmaxrobful]

at 14:07 you mention good time to sync butterflies, what's the best method to do this?

[@joewg3]

I've got this on my '85 50HP. When adjusting the rich/lean screw - which direction turns for rich/lean? I'm assuming that right = leaner, but I can't seem to get it right. My plugs are still too wet.

[@swblack1216]

Love your video’s my question are there good after market carb rebuild kits.? I don’t have a lot of money.

[@zjparrish123]

The plastic peice between the two carbs that you said not to break what is the part number for that piece

[@ezequiel3342]

Great videos man! Question, what's the diameter of the fuel hose that goes into the carb? Thanks!

[@MerCSonL6]

Quarter inch inside diameter. Son

[@maurogarcia6650]

one question, the 0.4mm is measured from the float to the center of the main jet? or are they measured where the main jet begins?

[@maurogarcia9912]

[@MerCSonL6]

Correct. Son

How's it going man, I have the same carb on my 50 Merc, I rebuild it the other day but on the first set of fuel pump diaphragms I put the paper thin black one, then the thin tan one, then the thick black gasket. When I crank it it "pops once" every time but I was only able to make it run once. No matter if I choke it, prime it, it just pops and that's it basically. Any help is greatly appreciated, thank you for your time and I look forward to hearing back from you soon!

[@MerCSonL6]

Make sure your cylinders are firing in order. Son

[@walkersamericanoutdoors7840]

@@MerCSonL6 I appreciate the response, the firing order is correct, the first time I fired it up after the pump rebuilds i got it to start, idle and run decently well, then it died out on me after a few minutes and has been only "coughing" since

[@elrincondelmecanico]

Hi, i have a carburetor like this, is a wma model, where can I find the workshop manual?

[@MerCSonL6]

Amazon.com or ebay. Son

[@jonnewman1360]

Did you take off the black plastic that controls the opening and closing of the carb?

[@MerCSonL6]

The linkage in the middle I do.

[@jonnewman1360]

Thanks. Trying to find how to reinstall a plastic part that was inside the carb. Has two tabs and a hole between them. I didn’t know it was I there till I started tearing down the carb and it just fell out. Don’t know what holds it in

[@culleynewman5840]

Does the main jet have the big hole or small hole? Not a mechanic and took it apart 7 months ago and forgot

[@jamescraig8601]

​@@culleynewman5840 Next time takes lots of pictures. Sure saves an old man a lot of headaches. Me.

[@dmaxrobful]

@@jonnewman1360 I have this issue myself and just spots it goes inside the throat and the tip of the emulsion tube goes into it. So it sits cross ways in the air intake part of carb throat

[@jonnewman1360]

I had a small plastic piece looks like a cross circular and has tabs on the side fall out I found it in a diagram. Looks like it’s in the middle of the Carb. How to you reinstall that?

[@MerCSonL6]

You have to lower the main venturi, install then screw the main back up to tighten it. Be careful..... its brass. Easily bent.

[@stephenbonaventure9423]

Hey, I was wondering I just saw your video I have a 1980. 50 hp mercury. You did not show in detail how to sync the two carburetors at the end of your video. What position do the throttle butterflies need to be in? I take it. They need to be closed both of them when you sink it not open. I had a float stick on my bottom carburetor took both the carburetors off at the same time but the sync connector slipped off the bottom carburetor, so I just gently slipped it back on now. Bottom cylinders will not run but two cylinders run fine good I have a fuel pump problem maybe?

[@RonnyGee]

I have a 1984 (from what I could find running the sn 50hp 2 stroke. Do you have to drop the bottom cowling to get the bottom carb off? The back half of the starter bracket(the part that is in the block) is in the way 😡

[@RonnyGee]

Btw it looks to be the exact same carbs as in this video.

[@MerCSonL6]

No you do not. It needs to be wiggled out. Son

[@JG-sk2tf]

You need to pull the starter. I cut a 7/16 wrench in half to get the bottom left nut. It fucking sucks. All the other nuts are easy. I recommend filling removing the blue side pieces fiest then removing the top carb first for maximum room getting to the bottom carb left nut.

[@L2fish]

Note to self. Don't lose the little metal insert in the linkage. Had to make one out of a can lid

[@kevdmiller5150]

What kind of motor is this from and would the kit work on a 83 mercury 50 hp 2 stroke?

[@timber5893]

How positive are you that this is the proper order of the gaskets on the fuel pump part?

[@MerCSonL6]

I have a mercury outboard service manual.

[@4x4BMW]

I'm curious to this as well .

[@4x4BMW]

I'm going with it has to be a misunderstanding .. It should be paper gasket tan gasket with the valves rubber gasket with the valves Then the center plate. Otherwise the tan gasket and rubber gasket can't sit flat against the back of the center plate.. not saying it would never work but not everybody's going to be lucky if they put it the other way . I did review a manual

[@jsolo7576]

I have a Mercury classic 50 two stroke. Will this kit work for my carbs? Thanks

[@MerCSonL6]

If you have the side bowl fuel pumps on both carbs it will work. Son

[@aarongagnow6027]

My carbs are leaking out of the blue caps. Any idea on a fix?

[@MerCSonL6]

Improper tang settings. Son

[@Tenbeerz1]

Wow, I needed this video. Can you post the rebuild kit #'s Thanks

[@Tenbeerz1]

NVM I see you showed them

[@bobsheller1427]

Didn't know these existed. What year outboard is it?

[@MerCSonL6]

1982 surprisingly. Adi ignition model. Son

[@bobsheller1427]

@@MerCSonL6 Wow, okay thanks Son.

[@michaeladams8022]

I have these same carbs for my motor, I just rebuilt them. Now when I prime my bulb, I have fuel squirting out of the vent hole on the bottom of the fuel pump. I dissassembled again and all the gaskets are aligned properly. Any ideas where my issue is?

[@JG-sk2tf]

I had this same issue, it's not a vent hole. Your blue plastic pieces on the sides of the carb are improperly seated. It drove me nuts and I ended up replacing them because I think they were warped from heat.

[@geoff8253]

The filters that you use in this video makes it difficult to see exactly what you’re doing and what you’re measuring

[@MerCSonL6]

I apologize. Son

[@biggnigg9265]

@@MerCSonL6 better fix this

[@MerCSonL6]

@biggnigg9265 the engine runs to this day. It belongs to a friend of mine. If it's not broken do not fix it. That's a boating rule.

[@shetonvue2948]

Would this rebuild kit work on a 1987 45hp mercury classic

[@MerCSonL6]

If you have the same carbs..... yes, it will. Son

[@kermitskustoms]

How do I tune these carbs?

Hello where i can buy carb+pump? I have issue with fuel pump on my 50hp 2 stroke 1983

[@rubenwright4133]

I have this exact motor, having trouble with it when I put in fowrd gear in the water, it stalls out. I can give it gas in neutral then slightly pop it back in forward to getting going. Once it gets going it runs fine until it idles then it dies. What could the issue be? I've tried everything and still have this problem.

[@rubenwright4133]

Also, does the carbs have carb covers? I was told that's why mine wasn't running right, that it's missing the carb covers.

[@MerCSonL6]

There's a fuel delivery issue is what it sounds like. When's the last time the carbs were rebuilt? Son

[@ConsumeYourSoul619]

the screw for the float bowl on the bottom carb backed out and your crushing it with the cable linkage. or at least that's what happened to me when i had that problem.

[@kelton5020]

That bowl was leaking gas, that's normal?

[@MerCSonL6]

Carbs will always leak a little. Not a fan of these carbs. Once the engine was running it had zero leaks. Son

[@caryhendrickson481]

Would be a better video if you didn't do so much with the effects really annoying while trying to watch! Other than that I enjoyed the video!

[@deonfraser4545]

You put the Gaskets in the wrong order.

[@MerCSonL6]

It works both ways. Son
